Specification of Letters Patent.

Patented July 13, 19261 Application filed October 12, 1917. Serial No.198,169.

- and residents of Brooklyn, in the county of Kings and State of NewYork, have invented certain new and useful Improvements in Closures forJars, Bottles, and other Receptacles, of which the following is a specification. The invention resides more particularly in a cap of tin orother suitable metal, with a special compressible gasket in the flangeor skirt portion thereof, adapted to the effectual sealing of glasstumblers, jars and other containers or receptacles having smoothexterior surfaces of substantially rigid or unyielding character.

One purpose of the invention is to provlde a cap and gasket readilycapable of being eflectually sealed against the exterior surfaces of aglass tumbler or like container by pressure applied downwardly andannularly' against a beaded portion of the skirt of the v cap holdingthe gasket to be compressed against the exterior surface or wall of thecontainer. 1 r 7 Glass tumblers and like containers are diflicult toproperly seal owing to defects in the upper edge portions thereof due tothe conditions under which such containers are manufactured, and as anillustration we may mention that the upper exterior surfaces of thecontainer, while intended to be straight, are frequently tapered, andalso that while the upper portions of such containers are supposed to betrue they frequently have irregularities in their surfaces and in manyinstances have what are called crizzles, which are very fine grooves orthe like sometimes almost imperceptible to the eye or touch, but uitesuflicient to prevent, under many con itions, the hermetic sealing ofthe container by many of the closures at the present proposed. One ofthe principal purposes of our invention is to provlde a closure whichmay be utilized in the efiectual sealing of a contalner, regardless ofthe usual irregularities in the exterior surfaces of the upper endportion thereof and regardless of such irregularities and crizzles asmay be present along the upper edges of the container.

In carrying out our invention we provlde a metal cap adapted to passdownwardly over the upper end of the container and having a dependingencompassing flange or skirt portlon which is shaped or groovedtorecelve the gasket or packing ring, said flange or skirt portionhaving a plain upper peripheral section and the groove or beading 1nsaid flange being located below said plain section and projecting onannular lines outwardly from the vertical plane thereof and adapted toreceive the gasket or packing ring. The cap and gasket or packing ringare of such dimensions with relation to the upper outer portions of thecontainer that they closely fit upon the same when applled thereto, andthereafter the scaling is eflected by a downward pressure against theupper outer portions of the beaded section of the flange, whereby saidsection and the gasket or packing ring contained therein are presseddownwardly and inwardly toward the outer walls of the container, withthe result that the said gasket or packing ring becomes greatlycompressed against the walls of the container and is held in suchcondition and position by'the beaded section of said flange, said gasketor packing ring then providing an effectual seal of adequate arearegardless of the usual irregularities that may be present in thecontainer. The compression of the beaded section of the flange or skirtportion of the cap and the gasket or packing ring held thereby alsoresults in the lower edges of the packing ring being squeezed downwardlybelow said section of the cap, and this is imv portant since by reasonthereof a person desiring to open the receptacle may, with a fork orother instrument, draw the packing ring downwardly from the cap, thusbreakgasket being illustrated in their initial con dition or before thesealing step of the process has taken place;

Fig. 2 is a like view of the same showing the relation of the cap,gasket and tumbler, after the beaded sect on of the flange or skirtportion .of the cap has been driven downwardly and inwardly, to compressthe gasket against the container;

Fig. 3 is a vertical section of a fra 'mentary portion of the container,cap and gas ket in their initial relation, together with a sectionalportion of a cylindrical tool by which the beaded section of the flangeor skirt portion of the cap and the gasket or packing ring held thereby,may be pressed inwardly and downwardly toward the container or to thecondition shown in Fig. 2;

F ig. 4 is a like View of the same showing the relation of the partswhen the applying tool has been driven downwardly to compress the gasketagainst the container;

Fig. 5 is a sectional fragmentary view corresponding with Fig. 3, butillustrating a modified form of the beaded section of the flange or.skirt portion of the cap, and

Fig. 6 is a like view of the same showing the relation of the partsafter the applying tool has been driven downwardly against the beadedsection of the flange or skirt portion of the cap to compress the gasketheld thereby against the exterior surfaces of the container.

In the drawings,referring to Figs. 1 to 1 inclusive, 10 designates acontainer, which may be a glass tumbler, 11 the cap,'12 a downwardlydepending flange or skirt constituting a portion of said cap and in itsupper part adapted to closely fit upon the upper exterior portion of thecontainer, 13 an annular beading formed in the lower portion of saidflange or skirt, and 14; the gasket disposed within the groove formed insaid beading andadapted toengage the exterior wall of the container 10.

The container 10 has plain exterior walls, and the cap 11 is adapted toclose the upper end ofthe container and at the upper portion of itsflange or skirt 12 to snugly encompass the upper outer walls of thecontainer. The beading or grooved portion 13 of the capmay be of variedformation, but the preferred construction thereof is illustrated inFigs. 1 to 4 inclusive, in which it may be seen that the upper portionof the beading 13 has a wall 15 which diverges downwardly and outwardlyin a direction from the container and that from the lower outer edges ofsaid wall 15 a vertical wall or flange 16 extends downwardly and setsoutwardly from the side wall of the container. The normal condition ofthe walls 15, 16 constituting the beading 13 is shown in Figs. 1 and 3,and within said beadingis located the compressible vertically elongatedgasket or packing ring 14 having anupper downwardly and outwardlyinclined surface corresponding with the wall 15 of the bead-.

the beading 13 may be turned inwardly to I a slight extent, as shown inFigs. 1 and 3,

' so as to facilitate the assembling of the cap its lower inner edgesinclined downwardly and gasket and the application of the same inassembled condition upon the container.

In accordance with our invention we de-- press the beading 13 and gasket14 downwardly and inwardly tpward the container and at the same timematerially elongate the same, the gasket being elongated by itscompression inwardly to a materially reduced thickness, and the headingbeing elongated by having its walls depressed downwardly and movedinwardly toward the container. The gasket and heading are by the methodof applying the closure-to sealing position, transformed from thecondition in which they are represented in Fig. '3 to that illustratedin Fig. 4. The compression of the gasket 14: results in the lower edgesthereof being protruded below the lower edge of the heading 13, and thishas the beneficial effect of so exposing a portion of the gasket that bymeans of a fork or other convenient means the gasket may be extracteddownwardly from the heading when it is desired to remove the cap fromthe container. The

beading 13 is open at its lower end and thus no difliculty isexperiencedduring the compression of the beading and gasket in causing aportion of the lower edges of the gasket to become exposed below thebeading.

The preferred method of compressing the beading 13 and gasket 17downwardly and inwardly toward the container is indicated in Figs. 3 and4 and comprises the employment of a cylindrical tool or die 17 havingand outwardly, as at 18, and its surface above said inclined portion 18vertical, as at 19. The die 17 is cylindrical and hollow and of therequisite predetermined inner diameter to eflect, when moved downwardlyon the cap, the compression of the beading 13 and gasket 14 downwardlyand inwardly or transform the same from their condition represented inFig. 3 to that illustrated in Fig. 4.

We deem it ofimportance that the beading 13 is below an upper plainsection or .portion 20 of the flange 12 and that the lower edges of saidbeaded portion 13 are open and away from the container so that thegasket may be caused to protrude downwardly below the said beadedportion when the cap is in final position on the container. The walls ofthe container are unyielding, and hence with a cap and gasket of thecharacter shown and described we are enabled to secure a very effectualsealing of the container and one which is efficient notwithstanding. anyirregularities, crizzles or the like that may be present around theupper edges of the container. The closure of our invention is entirelyeflicient whether the walls of the container are straight or beveled.

that the downwardand inward pressure of the heading 13 and gasket 14will make an eflicient seal regardless of whether the upper exteriorwalls of the container are vertical or tapered.

In Figs. 5 and 6 we illustrate a modified form of the closure, andtherefore in these figures number the cap 22, its flange or skirtportion 23 and its beading 24. Within the heading 24 is formed anangular groove holding a gasket or packing ring 25 which is of ob ongshape in cross-section, be-

ing thicker vertically than in width. The

lower end of the heading 24 is open so that finally the gasket may havea portion of its lower edges squeezed downwardly therefrom, and themetal at the lower outer edge of the beading 24 may be flanged inwardlyto a slight extent to facilitate the assembling of the cap and gasketandthe application of the same in their assembled condition upon thecontainer 10. The normal condition and relation of the heading 24 andgasket 25 are illustrated in Fig. 5, while in Fig. 6,

the said beading and gasket are shown in the relation they occupy afterthey have been acted on by the tool or die 17 to compress the beadingand gasket downwardly and inwardly toward the exterior wall of thecontainer, the said heading and gasket being,

during and b this operation, vertically elongated and tii squeezed fromthe lower edges of the beading, so that said edges of the gasket becomeexposed, as in the constructlon shown in Fig. 4. When the beading 24 andasket 25 are moved downwardly and inwar ly toward the container by meansof the die 17 said heading and gasket take substantially the outlineillustrated in 4, as will be understood on reference to I ig. 6.

Our invention comprises the cap having the lower heading in its flangeor skirt and a gasket within said beading, said beading being open atits lower end and said beadthe invention to details otherwise than theappended claims may require.
